FOLDING BED.

Specification of Letters Patent.

Patented Aug. 8, 1922.

Application filed December 2, 1920. Serial No. $27,755.

To all whom it may concern 1 Be it known that we, THOMAS A. LoeAN, JOSEPH F. BROWN and CHARLES E. DAVIS, citizens of the Umted States, and residents of Kansas City, Jackson Count- ,Missouri, have invented a certain new an useful Improvement in Folding Beds, of which the ollowing is a complete specification.

This invention relates to folding beds of that class in which provision is made for accommodating a full-width mattress, and the primary object is to produce a folding bed of this type which can be moved and-opened and clomd easily, cannot close accidentally, and in which the mattress and bedding is held firmly against displacement when the bed is closed or bcin opened. A further object is to produce a folding bed possessing the features of advantage set forth as de sirable, which is of attractive appearance and of comparatively inexpensive construction.

With the above mentioned objects in view, the invention consists in certain novel and useful features of construction and combinations of parts as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawings, in which Figure 1, is a broken vertical section of a folding 'bed embodying the invention, the section being taken on the line II of Figure 2.

Fi re 2 is a horizontal section taken on the line HII of Figure 1.

Figure 3, is a section corresponding to Figure 1, but showing the bed in a partially folded position.

Figure 4:, is a section corresponding to Figure 3, but showing the bed in fully closed position.

Referring now to the drawings in detail, Where like reference characters identify corresponding parts, 1 indicates apair of parallel base bars formed or provided at their front ends with upwardly projecting arms and connected together at their rear ends by a head frame 2, said head frame being preferably of greater width than the distance between the said parallel bars. The rigid frame constituted by said bars and said head frame, is mounted upon suitable casters 3 for convenience in rolling the bed in any direction. The side frames, consisting of said bars and their upwardly projecting arms, are rigidly connected together by one or more cross bars 4, and the upper ends of the said arms are formed with pivot sockets 5, receiving the inwardly-projecting adapted to rest, it being noted that the fabric 10 occupies a position above the plane of the pivotal point of said rectangular frame, and that said fabric lies between the head frame 2 and the arms of the bars 1, when the bed is closed, as shown by Figure 4;, and it will also be noted in this connection, that the sup-porting arms do not in anywise interfere with the use of a mattress of the same width as the head frame 2, as said mattress when in vertical position is above the base bars 1 and projects beyond or overhangs the same at their outer sides. It will thus be apparent that the frame of the bed need not exceed in width the regulation Width mattress in order to accommodate the same, as is usually the case with folding beds of this character.

The foot frame 11 of the bed is pivotally connected by pairs of links 12 and 13 to the side rails 7 of the rectangular mattress frame, and said links are so positioned and proportioned that when the bed is in opened position, the foot frame bears against the foot rail 8 and the links brace said foot frame in vertical position, the said links when the bed is in folded condition, permitting the foot frame to occupy a vertical position adjacent the vertical plane of the side rails of the bed, and said foot frame is mounted upon casters 11 so that when the bed is opened it may be readily moved upon the floor without necessitating the lifting of the foot frame.

A pair of rocker bars 14: are fulcrumed at 15 to the base bars 1, the head ends of said rocker bars being connected by retrac-tile springs 16 to brackets 17 secured rigidly to the head frame by means of cross braces 2 thereof or in any other suitable manner. The opposite ends of the rocker bars 14 are connected by retractile springs 18, to a pair of arms 19 rigidly secured to the pivot studs 6 of the mattress-carrying frame. The springs 16 and 18 are under tension which is greatest when the bed is springs-16, but sufiicient to hold the mat tress-carrying frame in vertical position, and in the unfolding operation said springs 18, are first tensioned before applying suflicient pull on the rocker levers 14 to effect appreciable stretching of the springs 16.

The springs 16 and 18 conjointly as above.

indicated hold the mattress-carrying frame in vertical position, but to guard against any possibility of accidental unfolding action of the bed, the head rail 8 is provided with a pair of beveled teeth 20 adapted "as the mattress-carrying frame swings downward to a horizontal position, to slightly repress a pair of spring arms 21 carried by the head frame, and then clear the ends of said arms, which instantly react and thus occupy a position rearward of said teeth and guard against accidental folding operation, or the tipping of the head frame over upon the bed should pressure be applied forwardly on the head frame or foot frame in moving the bed. The head rail 8 is equipped with a frame 22 to abut against the head end of the mattress when the same is resting upon the fabric 10, and any suitable foot clamps, not shown because in common use, may be provided to clam the foot-end of the mattress to its supporting frame.

A pillow and mattress clamping frame 23 is pivoted as at 24 to the frame 22, and said frame 23 at one end has an arm '25 pivotally connected by a curved link 26 with a swing arm 27 pivoted to the inner side of the adjacent arm of one of the base bars 1, this method of linking the said parts together permittino the clamp frame 23, when the bed is fol ded, to swing forwardly and apply pressure upon the pillows, not shown, to clamp the same, the bed covering and the mattress firmly in place, at the same time permitting the head end of the mattress-carrying frame to swing downwardly between the head frame and the upwardly projecting arms of the base bars, as shown most clearly in Figure 4. In this connection it will be understood that the clamp ing movement of the frame 23 occurs be cause of the relative change of positions between the frame 22 turning around the pivotal point 6, and the links 27 fulcrumed or pivoted eccentrically of said pivotal point 6, and that when the bed is unfolded, the eccentricity of said pivotal points, results in the opening movement of the clamping frame, as will be readily understood by reference to Figures 1, 3 and 4 of the drawlngs. v

To unfold the bed, the foot portion is pulled downward to impart movement in the same direction to the mattress-carryin frame, this movement being easily eifecte because the resistance of the springs 18 and 16 is-successivel-y overcome, that is to say springs 18 yield to the initial part of the movement and the gravitative tendency of said frame assists the operator in overcoming the resistance of the stronger springs 16. In the reverse of closing movement,

both sets of springs aid the operator who striking the woodwork and marring the same. To accomplish this, a hook 28 is secured to the head frame and slidingly engages a suitably-supported guide rail 29, adapted to extend from a point within such closet to one of the stiles of the closet doorway. As it is not new to dispose beds in closets during the day, the drawings (Figure 1), only show the slidable interlocking relation between the rail and the hook.

From the above description it will be apparent that we have produced a folding bed embodying the features of advantage set forth as desirable in the statement of the object of the invention, it being under stood that we reserve the right to make all changes within the scope of the appended claims.
